        title: 'Software Engineer')
  @name = "#{first_name} #{last_name}"
  @birthday = Date.parse(birthday)
  @title = title

def new(
  first_name: 'Ben',
  last_name: 'Hamill',
  birthday: '1982/02/13',
  title: 'Software Engineer'
)
  @name = "#{first_name} #{last_name}"
  @birthday = Date.parse(birthday)
  @title = title
end

def new(
        first_name: 'Ben',
        last_name: 'Hamill',
        birthday: '1982/02/13',
        title: 'Software Engineer'
       )
  @name = "#{first_name} #{last_name}"
  @birthday = Date.parse(birthday)
  @title = title
end

I hate the first one least.

I started with #2, but the same-indent-levelness of the method body is bad. Here is another:

def new(
    first_name: 'Ben',
    last_name: 'Hamill',
    birthday: '1982/02/13',
    title: 'Software Engineer')
  @name = "#{first_name} #{last_name}"
  @birthday = Date.parse(birthday)
  @title = title
end

The same way as my non-keyword arguments, of course:

def new(first_name: 'Ben', last_name: 'Hamill', birthday: '1982/02/13',
        title: 'Software Engineer')
  @name = "#{first_name} #{last_name}"
  @birthday = Date.parse(birthday)
  @title = title
end
